Good quality

I bought this for my wife for her birthday. The infuser is high quality. The glass, metal, and wood are all well made. The constellation art is crisp and easy to read.

Perfect Gift for the Tea Sommelier!

My wife absolutely loves this very elegant infuser. While she may not really be a Tea Sommelier, she is a true Tea Connoisseur who is always looking for a "better infuser". The Cognitive Surplus Night Sky Tea Infuser has really been an ideal gift and has been used regularly since opening on Christmas morning. The stainless basket is a bit challenging to remove without popping off the wire handle, but we figured it out with a little twist, it pops out much easier.

Perfect size Nice, hot tea on the go Would recommend


I absolutely love it but...

I bought this for myself after my family stole all my other tea infusers. I loved it so much and took such good care of it but recently I was handwashing it and since the bottom is so thin I applied a bit to much pressure and it broke. I was really sad and I would love to buy this again if they make the bottoms a bit thicker. Just be careful with cleaning them. Overall the design is really beautiful and it made my friends jealous.


I can't rave about these guys enough. Somehow my address in etsy was my old one, so somehow probably my fault, and they shipped it there. I couldn't get it, so they sent me a free replacement! that one got broken in the mail so they sent me a THIRD one! Just because they're nice! and didn't kick up a fuss at all!!!! Not to mention I love this so much. I'm an herbalist so this way I can have my herbal loose teas allllllll the time. Its beautiful, art, functional, and the thing that holds the tea leaves is hands down the best tea infuser ever. I love it.
